Pasadena, CA Bridge Collapse, Oct 1972

BRIDGE COLLAPSES, 6 WORKMEN KILLED.

Pasadena, Calif. (AP) - The bodies of three workmen entombed in a 100-ton slab of concrete were found today by rescue workers who used jack-hammers to rip through debris of a fallen 100-foot-high freeway bridge section. The discovery brought the death toll to six.
Three other workmen were killed Tuesday when the timber and steel beam structure plunged to the ground carrying dozens of workers with it.
An additional 21 workers were injured and six were hospitalized in critical condition today.
An intense search by more than 200 men was conducted throughout the night despite the threat that other parts of the bridge, part of the Foothill Freeway, might collapse on them.
A spokesman for the Pasadena Police Department said the bodies of the final two victims were found in the 100-ton slab of cement after crews using jack-hammers
riddled the slab for more than an hour to free the body of another of the victims.
Concrete was being poured into wooden forms when the center section of the north side of the bridge gave way, cascading into the ravine about two miles north of the Rose Bowl. The framework of the south side of the giant bridge, poured earlier, remained intact.
Jimmy Fultz, 45, a workman who was standing on an adjacent span when the north side collapsed, said, "I heard it go 'whoom'. I ran back from where I was working. Those guys working on the deck in the center had no chance. I saw some of them go down with it all."
More than 200 men, most of them volunteer construction workers, worked through the night under a battery of powerful floodlights. Steel girders and large planks of lumber dangled menacingly from the tattered edges of the bridge above them.
The cause of Tuesday's collapse was not immediately determined, but police said it appeared that metal beams supporting the concrete forms on the north side failed to hold the additional weight when the concrete was poured.
